1. A self-vibrating pH probe comprising:
a housing containing an electronic assembly adapted to support detecting pH of an environment;
a vibration source disposed so that at least a portion of vibrations caused by the vibration source propagate to the electronic assembly, the vibration source being controllable for at least on/off operation;
a pH probe member having a probe tip at a first end, the probe member extending from the housing and mechanically and electrically coupled by a second end to the electronic assembly so that at least a portion of vibrations propagating to the electronic assembly further propagate to the probe tip; and
a processor coupled to the electronic assembly and adapted to coordinate operation of the vibration source and operation of the pH probe member including controlling when the vibration source is activated relative to when a sample of pH is taken by the pH probe.
